Association between the respiratory severity score and extubation success in severe bronchopulmonary dysplasia.
Observational study in Journal of perinatology : official journal of the California Perinatal Association, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveCharacteristics associated with extubation success (ES) in established grade 3 bronchopulmonary dysplasia (G3-BPD) are unknown. The respiratory severity score (RSS) is associated with extubation failure in younger preterm infants and adverse outcomes in established BPD. We evaluated the association between the RSS and ES in G3-BPD. STUDY
designRetrospective observational study of infants diagnosed with G3-BPD undergoing their first extubation attempt after 36 weeks postmenstrual age (PMA). Bivariable and multivariable logistic regression models were used to determine the associations between RSS and ES while adjusting for confounding characteristics.
resultsAmong 239 infants with G3-BPD undergoing an extubation attempt with a median RSS of 3.0, 142 (59%) were successful. A higher RSS was associated with lower odds of ES in adjusted analysis.
conclusionRSS is independently associated with ES in infants with established G3-BPD undergoing their first extubation attempt after 36 weeks PMA, with lower odds of success as RSS increases.
